(BUDDHA) - John Pourner is looking for his 32-year-old daughter Alicia Pourner and her boyfriend 30-year-old Lucas Karn.

Both are developmentally disabled and neither can drive. John believes they are with a third party in the Kenray Lake area.

John does not believe they are in danger, but his daughter is on medication for seizures and tremors and didn't take her medication with her when she left.

Alicia and Lucas Karn went missing Saturday.

Alicia is 5'1" and 190 pounds with black hair and blue eyes. She was last seen Saturday in the Buddha area and was wearing a brown T-shirt with a picture of a dream catcher with a wolf superimposed over it, and dark blue shorts. Karn is 5'11" with black hair and blue eyes.

Lawrence County Sheriff Sam Craig says the two were reported missing to police Saturday, but the family didn't want to publicize anything, because they believed they would be found quickly.

Pourner says as the weekend passed, and they were not found, family members changed their minds about asked the public for help locating the couple.

Craig says investigators and family members are pursuing leads. They, however, have been hindered somewhat because the third party involved is not cooperating.

Anyone with information about their whereabouts is asked to call police or John Pourner at (812) 545-9046.
